Currently, 20 per cent of companies with multiple locations are testing IP (Internet Protocol) telephony over their local area networks, as a potential replacement for their corporate phone systems. An additional 25 per cent will initiate trials this year. By the end of 2001, almost half of US companies will have moved from trials to formal implementation. According to a recently published study by the Phillips Group (http://www.thephillipsgroup.net), the current obstacles surrounding reliability, quality of service and scalability of IP telephony will be resolved over the next 18-24 months. "The question, then, is not whether to switch to IP telephony over the LAN, but when and how", said Terry White, senior director at the Phillips Group, and lead analyst of the landmark IP telephony study. The results of the study were presented at VoiceCon2000, the 10th Annual Conference on Enterprise Voice Communications, in Washington DC, and the session offered an analysis of how the $16 billion US CPE (customer premises equipment) market will transition to IP telephony. The analysis was based on primary research involving over 500 PBX customers to determine key market drivers, test the value of the IP business case, and analyse the buying behaviour, adoption patterns and decision processes related to IP telephony.
